That geometric chuck is a fantastic widget! I have always drooled over what Holtzapffel ornamental lathes can do. I set up a Supershop lathe to mimic some of the simple patterns, but simple is the key word. The geometric chuck video reminded me of the Spir-o-graph toy. Years ago I gave up trying to think about linking that.... but now I can cut gears. Hmmmm.
Your geometric chuck for the LOM is in another class! WOW! First question (suppressing many others) is how do you cut those gears? I have a gear geometry program to create a printed pattern, but cutting it on the scroll saw seems to lack the accuracy that is desirable. They are just spur gears, so an indexing head on a mill ? This would be way overkill for the trammel, but I LOVE overkill. Ivandea. If one used narrow timing belts, would that eliminate a lot of the gears?
